Has Psylocke ever had a good one? The most positive I can think of is Angel, and that ended up being toxic in the end. Then there was Fantomex, which was toxic. Then Cluster, who left her for Fantomex, so not great. When Cable clones.
Not that I wish none of those had happened. They were good story elements; it just happened the good story concerned unhealthy relationships.
Hazmat and Mettle were a love too pure for this world.
Don't let the X-boards find out about this or you'll get buried by a certain faction.
